Evaporator Low Fin Tube Heat Exchanger Condenser N Type
Heat Exchanger Condenser Evaporator Low Fin Tube N Type
Our Materials
We offer you a broad portfolio of materials and can expand our offering at any time to meet your specific needs regarding thermal conductivity, mechanical properties, or corrosion resistance. Low-finned tubes made by Wieland Thermal Solutions are already available in copper, copper-nickel, brass, carbon steel, stainless steel, and titanium.
- The ‘Low Fin Tube’ is also known as Integral Fin Tube. This type of fin tube is widely being used in the Industry Today.
- The Low Fin Tubes/Integral Fin Tubes are increasingly being used in various Fluid Heat Exchangers. Unlike other Fin Tubes the application is not limited to Air – Fluid type of heat exchangers. As a result they are used in various types of Shell And Tube heat exchanger also.
- The fins are manufactured rolling the Fin in the Base tube Itself. The fin height is relatively very low. However number of Fins Per inch or the fin Density can be increased greatly and improve the heat transfer area. The rolling is done on a special machine and the same can be supplied in straight as well as U bend configuration.
Quick Detail:
| General Low Fin Tubes Production Capacity | Specifications of Low Fin Tubes('N' Fins) |
Finning Facility: 10 finning machines; Daily capacity up to 3000 meters; |

Delivery Range of Low Fin Tubes
We can provide the integral low fin tubes with un-finned section gaps( 5mm Min.) in the middle of core tube OR bent with designed Bend Radius.
Quality Test:
The integral low fin tube quality is assured by hydrostatic or pneumatic tests, eddy current tests & MARCO tests in order to verify design specifications.
Acceptance Ceritia:
WOLVERINE / HPT / GEWA-K & GEWA-KS
Delivery Condition:
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish.
The desiccants are put into the each package for continental transportation.
Applications:
The Integral Low Finned Tubes find the preference in the following industrial sectors:
- Heating systems
- Ventilation systems
- Refrigeration and climate control systems
